You might be thinking that it is hard to believe that wu-yi tea can do all these amazing things. However, various studies and research support wu-yi tea’s ability to promote weight loss naturally. According to a study conducted by University of Tokushima’s School of Medicine in Japan, drinking wu-yi tea can boost the metabolic rate by as much as 10% among Japanese women. Another similar study showed that consuming three to four cups of the dark-colored beverage a day can help you lose up to 15 pounds. Although much of your weight loss depends on how often you exercise your body, as well as on your daily food intake, these studies revealed that drinking wu-yi tea can help speed up the process of shedding unwanted body fat.
